Paper Title:
Influence of Sulfide on Anti-Corrosion Performance of Passive Film Formed on Stainless Steel in Borate Buffer Solution
  Abstract

The semiconducting behavior of passive film formed on 316L stainless steel in borate buffer solution containing sulfide was studied by capacitance measurements. The results indicate p-type semiconducting behavior related to chromium oxide of the passive film at -1.12 ~ -0.78V and n-type semiconducting behavior to iron oxide at -0.47 ~ +0.35V, with an acceptor density 11.21020 cm-3 and a donor density 7.501020 cm-3 respectively. The existence of sulfide in the solution obviously increases the acceptor densities which reaches to 215.61020 cm-3 with the sulfide concentration of 12 mgL1, and therefore have a more conductive behavior.
